[V8] Oil Leak Suggestions?

[cobram at juno.com]

I have this same enigma in V8Q #1, and to a lesser extent in #2.  With
all the usual suspects ruled out (valve covers, primary and secondary oil
pan, oil pump etc.), the best I can figure with the use of black light
and some extrapolation, is that the leak is coming from the "sealing
flange."  

Check ETKA illustration 2-50, part #18 here:

I've had the mystery leak for about 5 years now, good news is that it
doesn't get worse (or better either.)  Leak volume is steady.
It seals along the front of the block, without tearing the engine down,
it's the best I can figure.
